initial node registration.
* Changes in SLURM 0.3.0

-- Add support for "hidden" partitions (applies to their
nodes, jobs, and job steps as well). APIs and commands

of the allocation rather than the user making the allocation
request (user root for LCRM batch jobs).

more than one numeric field in node name).

still processing job completion. This will work properly for
shared nodes.

-- Fix for file descriptor leak in slurmd.
-- Propagate stacksize limit to jobs along with other resource limits
that were previously ignored.
===============================

scalability.
-- New sinfo option "--list-reason" or "-R". Displays down or drained
nodes along with their REASON field.

-- Sinfo sort partitions in slurm.conf order, new sort option ("#P").
-- Document how to gracefully change plugin values.
-- Slurmctld does not attempt to recover jobs when the switch plugin
value changes (decision reached when any job's switch state recovery
fails).
-- Node does not transition from COMPLETING to DOWN state due to
not responding. Wait for tasks to complete or admin to set DOWN.
-- Always chmod SlurmdSpoolDir to 755 (a umask of 007 was resulting
-- Return errors when trying to change configuration parameters
AuthType, SchedulerType, and SwitchType via "scontrol reconfig"
or SIGHUP. Document how to safely change these parameters.

moved from common into plugin modules.
-- Documentation for writing scheduler, switch, and job completion

throughput (resulted in job inactivity limit being reached improperly
when hundreds of jobs running simultaneously)
===============================

clusters with FastSchedule configured off

===============================
-- Fix bug where early launch failures (such as invalid UID/GID) resulted
in jobs not terminating properly.

=========================
-- Fixes for reported problems:
- slurm/265: Early termination of srun could cause job to remain in queue.
- slurm/268: Slurmctld could deadlock if there was a delay in the
termination of a large node-count job. An EPILOG_COMPLETE RPC was
added so that slurmd could notify slurmctld whenever the job
termination was completed.
